J e it known that l. o Snow, e citizen of the United States. residing at Lawrence, in the county otf and State of Na?- chizs-co s have i vented an Ei11} 3l"OV81 in lleeler lijieohanuns for Looms. ofwhich the following description. in connection with the accompanying; drawingsis a specification. like characters on the drawings repressntinglike parts This invention relates to Ieeler mechanism :toi' looms whereby. the filling is replenished from time to time While the loom continues to run.

It is now the common practice to Wind the filling: or .wett thread upon the filling; carrier or hohhin in conical Wind tormetions known as filling Wind. Fihonld the t'eeler encounter the conical formation of the filling wind on detecting heat. it is liahle to be given its movement to ettect noplenishincnt of lilling prematurely and Willie there still remains Within thecshuttle a working; supply of filling. This ohjectionahle condition is most clearly manifested in that type of teeler mechanism wherein thc Peeler is mounted to enter the shuttle in a direction inclined to the longitudinal axis of the shuttle. although it may take place in toeler mechanisms of other types,

Should the teeter call for a change of filling prematurely. objectionable Waste of filling is liahle to occur. While on the other hand it the teeler fails to call for a change oi: filling when the filling is substantially exhausted on a detecting hea defective cloth is liable to he produced.

(hie of the oh iects oi? the presentv invention. therefore. is to provide a feeler mechanism which will be prevented from effecting replenishment of filling? While there still remains Within the shuttle a Working supply of filling and to permit the teeler to cell the change of filling when the filling is substantially exhausted on c. detecting; heat.

in ace rdance with the present invention the 'leeler mechanism comprises two feelers, both of which ent r the shuttle on c. detect in heat and teel tor the filling. one ot the feelers beingconstituted as a main teelei: and the other as an auxiliary teele for con trolling the filling: replcnishin movement ot the main t'eeler and prevent premature chance of filling; and et 'oei-mit such chance i 4 .7 l m of film when the filling in the shuttle has hecoine substantially exhausted.

The rear portion of the fe-eler stand is provided with a transversely extending guideway 10 for a laterally movable slide 11, llig. 3 which is provided with an opening 12 through which the teeler '7 extends. The slide 11 may he retained in its giiideway by a cap plate 13 secured to the rear portion of the iceler stand by screws or holts ll, and the slide 11, in the present instance, is show i as provided with a hip 15 to which is connected the t 'ansinitter 16.

The feeler 7 has secure (l to it a bridge or guide 17 between which and the tront hearing 8 is a spring 153 which normally acts to impel the feeler 7' reari'ardly, with permissive movement trontwardly. The parts so far described n a5 he oi the same ieral construction and ijnodeof operation as more fully shown and d i Edward S. Stimpson July 8, 1919, and as in se' 7 is provided with a tor i ein eging end portion 19. Tue eoiist'uction is such that on eacn detecting heat when a. working supply of filling is present in the shuttle and the cylindrical portion thereot is presented to the n ain tteeler, the toot filling engaging. end 19 will sink a mass of filling and hold the teeler int from its side swipe inovemen, or movement longitudinally along the filling carrier until the filling is sul'istantially exhausted on a detecting heat.

In accordance with the present invention, an auxiliary teelcr is provided which enters the shuttle and feels tor the filling on each detecting heat, and a locking novice hetween the main and an. 'liary 'hselers serves to prevent sine swipe ll'iOYOillCllll of the main :l eeler in case the diam iter oi the fillin in the shuttle which is presented to the n tin ii'eeler, is less than the diai'neter of the filling in the shuttle presented for engagement by the auxiliary iceler. hist trees the n'iain too to its side swipe movement should the di. eter oi? the filling' p= scnted to the main and auxiliary iteecrs he the sa no. in other words should the ai tiliar teeler first engage the filling in the shuttle. it will control the locking device to prevent side sii'ipe movement of the main feelcr on. a detecting heat, but should the main feeler first he moved frontwardly loy engageniient with. the filling, the locking device is rendered inetlective to prevent side swipe movement of the main feeler.

The auxiliary feeler 20 is shown as mounted for movement towards and from the front of the loom and as restrained from side swipe movement, and may he conven 1 ,eeenee o: convmieinlv termed as a part or or ed to the Leeler stand 4:. In the pres s ance. it is shor-ri as secure-d to the iteeler stand by means or a screw 52 itctween the it hearing 22 and a colla 2-34 on the an liar-'5, tee-lei there pose? is intc a, shrine; 23o which norn all holds the auxiliary l'eeler Lil in its rearward i eeli asindica cal Fl positizv t v in providing the rear searing for tl e auxiliary :t eler the slide ll hrough which niain tceler extends may he made shorter than the corresponding slide of the Stiinpson patent, as indicated in Fig. 2-3, so that the tront he ring for the Frl'ilwilllilll'ff fife hr 20 may be constituted as a hole or holes passed through the guideway forming members at the rear of the feeler stand. This construc tion is found. to he a convenient way of supporting the auxili: I teeler for movement towards an It'ron'i the front of the loom while resti iing' it from laeral or side swipe inoi .ient although other forms oi hearings may oi course be employed without departing; iron'i true purpose of the present invention.

i s feeling; position feel for the filling to the longitudinal this is tound to he a good form of the in vention where the main side swipe teeler is of the inclined type, as shown. lilowever the invention contemplates mounting the i'turdliary teeler 20 for n'ioveinent to wards and from. the front of the looin i'hile rest 'ained fronr side swipe inoven'ient and such characteristics of the aur-ziliary ieelc-r may be secured, even though the auxiliary feeler r aches rearwardly to its feeling posh tion in a. direction at right un les to the longitudinal axis of the shuttle.

Where the auxiliary ieeler 20 is inclined, as shown, it may be desirable to provide it. rea end portion with a move filling engaging element such for instance, as a roller 26, so that on the beat-up movement, the roller will roll over the filling to a slight extent as the auxiliary feeler is in ved frontwardly. In case the auxiliary teeler 20 is inclined, as shown, it may have sulir cient play in its front and rear hearings to permit it suilicient moven'ient without injurious ei'l'ect to the filling, even though the roller 26 be not employed.

Between the main and auxiliary feelers there is a locking); device which, as hereinhctore suggested, is eillective to prevent side swipe movement of the main feeler should the in a direction incline axis of the shutte, and.

1 ,aeeaoe auxiliary feeler first engage the filling on a detecting beat, as, for instance, when a conical portion of filling is presented for engagement by the main feelcr, but which is rendered ineffective to prevent such side swipe movement of the main feeler when the latter first engages the filling on a detecting beat,

The locking device, in the present instance, consists of a shoulder or hook 527 carried by the auxiliary feeler, and a reversely arranged shoulder or hook 28 carried by the main feelcr. The hoolr 27 is shown as frontwardly pointed, while the hoolr 28 on the main feeler is shown rearwardly pointed, the effect being that when the two are engaged, as shown in Fig. 1, side swipe movement of the main feoler is prevented. Although the locking device as shown is found to be effective and practical, it of course may be varied to carry out the purpose of the present invention, and in the present case the shoulder 28 on the main feeler is formed as part or secured to collar 29 which may be secured to the main feeler 7 in adjusted position by screws 30.

In accordance with the present invention, also, the filling engaging end portion 19 of the main feeler extends rearwardly a slight distance beyond the filling engaging end portion of the auxiliary feeler, so that should the cylindrical portion of the filling in the shuttle be presented for engagement by both feelers on a detecting beat, the main feeler will first engage the filling and be first moved frontwardly, as indicated in Fig. 2, to disengage the hooks 2"? and 28 on the auxiliary and main feelers respectively, or in other words, render the locking device ineffective to prevent side swipe movement of the main feeler, because at such times the toothed engaging end 19 of the main feeler will sinlr. into the filling mass and hold the main fceler from side swipe movement.

Only a portion of the lay and shuttle box at the fccler side of the loom are shown, because these parts may be of usual construction. The front wall 31 of the shuttle be is provided with an opening, as usual, for the entrance of the feelers, and similarly the front wall of the shuttle is provided with an opening 33 through which the feelmay extend on a detecting beat and feel for the filling in the shuttle. The filling is carried by a filling carrier or bobbin 84-, and as hereinbeforc noted, the filling 35 is wound upon the f ing carrier or bobbin in conical layers fr ,ni the head or base portion of the bobbin towards the tip, as usual. Under these conditions will be apparent that at times the filling engaging end 19 of the main feeler will have presented to it a part of the con cal wind and in the absence of any means to prevent it is liable to partake of its side swipe movement, but with the auxiliary fecler and locking device, substain lially as hcreinbefore (flescribed, such premature movement of the main feeler is pre- \e-itcd.

ll hen a working supply of filling is present in the shuttle on a detecting beat, and a cylindrical portion of the filling is presented for engagement by both the main and auxiliary feelers, the main feeler will first en gage the filling and be moved frmitwardly relative to the auni iary feeler to thereby render the locking device ineffective, as indica -d in 2, whereupon the main feeler is f ced to partake of HS side swipe movement but is held from such movement by the toothed end of the feelcr sinking into the filling, and this condition maintains during the entire beat-up moven'lent of the lay, as indicated in Fig. t. Should the conical portion of the filling wind on the filling carrier or bobbin be presented for engagement by the main feeler on a detecting beat while still a working supply of filling remains in the shuttle, the auxiliary feeler will first engage the filling, as indicated in Fig. 5, thereby causing initial frontward movement of the auxiliary feeler and maintain ing the locking device elfective to prevent side swipe movement of the main feeler, and this condition will continue until when the fillinghas been depleted to present a substantially cylindrical surface for engagement by both the main and auxiliary feelers, the main feeler will engage the surface within the shuttle in advance of the auxiliary feeler and render the locking device ineffective, thereby freeing the main feeler to its side swipe movement, as indicated in Fig. 6.

l Vhen the main feeler partakes of its side swipe movement, as indicated in Fig. 6, the slide 11 is caused to move laterally, substantially as in the Stimpson patent hereinbefore mentioned, and through the transmitter 16 call for a change of filling.

lVhat is claimed is:

1. In a feeler mechanism for looms, the combination of a main feeler which is mounted to enter the shuttle in a direction inclined to the longitudinal axis thereof and for movement longitudinally along the filling carrierto call the ch ange of filling, an auxiliary feeler mounted for independent movement towards and from the front of the loom and restrained from movement longitudinally of the filling carrier, and interlocking connections between the main and auxiliary feelers which prevent premature movement of the main fecler longitudinally of the filling carrier when. the auxiliary feeler moves frontwardly on a detecting beat before the main feeler is moved and which are disengaged when the main feeler moves frontwardly before the auxiliary feeler is so moved.

2. Is a feeler mechanism for looms, the combination of a main feeler which is mounted to enter the shuttle in a direction inclined to the longitudinal axis thereof and for movement longitudinally along the filling carrier to call the change of filling, an auxiliary feeler mounted for independent movement toward and from the front of the loom and restrained from movement longitudinally of the filling carrier, and locking connections between the main and auxiliary feelers which are normally engaged when the main and auxiliary feelers are both in rearward feeling position and which become disengaged by frontward movement of the main feeler before such movement of the auxiliary feeler on a detecting beat and which remain engaged to prevent premature call for replenishment by the main feeler when the auxiliary feeler is first moved frontwardly relative to the main feeler on a detecting beat.

3. Is a feeler mechanism for looms, the combination of two feelers which enter the shuttle on a detecting beat and feel for the filling, one of which is constituted as a main feeler mounted for movement longitudinally of the shuttle to call for a change of filling and the other of which is restrained from such movement, and a safety device comprising a lock normally positioned to pre vent movement of the main feeler longi tudinally of the shuttle on a detecting beat when both feelers are in rearward feeling position and movable into unlocking position to. permit such longitudinal movement of the main feeler when a cylindrical surface within the shuttle is engaged by both the main and auxiliary feelers on a detecting beat.

4. In a feeler mechanism for looms, the combination of two feelers which enter the shuttle on a detecting beat and feel for the filling, one of which is constituted as a main feeler mounted for movement longitudinally of the shuttle to call for a change of filling and the other of which is restrained from such movement, and locking connections between the main and auxiliary feelers which become unlocked when both feelers meet the same cylindrical surface within the shuttle on a detecting beat and remain in locked position when the auxiliary feeler meets and is moved frontwardly by a surface within the shuttle before the main feeler meets a surface within the shuttle.

5. In a feeler mechanism for looms, the combination of a main feeler mounted for movement towards and from the front of the loom and in a direction longitudinally of the shuttle, an auxiliary feeler mounted for movement towards and from the front of the loom and restrained from movement longitudinally of the shuttle, interengaging 1,4eaaos parts movable with the main and auxiliary feelers which become disengaged on a detecting heat When the main feeler meets the filling before the auxiliary feeler and which are engaged to lock the main feeler from premature movement longitudinally of the shuttle when the auxiliary feeler engages the filling before the main feeler.v

6. In a feeler mechanism for looms, the combination of two feelers which enter the shuttle on a detecting beat and feel for the filling, one of which is constituted as a main inclined feeler mounted for movement l0ngitudinally along the filling carrier by the frontward pressure upon it to call the change of filling and the other of which is constituted as an auxiliary feeler, and a safety device comprising a lock between the main and auxiliary feelers normally positioned to prevent movement of the main feeler longitudinally along the filling carrier until the main feeler meets the filling in advance of the auxiliary feeler whereupon the main feeler is freed for movement longitudinally along the filling carrier.

7. In a feeler mechanism for looms, the combination of two feelers both of which enter the shuttle on a detecting beat to feel for the filling, one of which is a main feeler mounted for movement along the filling carrier to effect replenishment of filling and the other of which is an auxiliary feeler restrained from movement along the filling carrier, a locking device between the main and auxiliary feelers effective to prevent movement of the main feeler in a direction longitudinally of the shuttle when the auxiliary feeler receives the frontwa-rd pressure of the filling in advance of the main feeler and is rendered ineffective to prevent movement of the main feeler longitudinally of the filling carrier when the main feeler receives the frontward pressure of the filling in advance of the auxiliary feeler.

8. In a feeler mechanism for looms, the combination of a main feeler which enters the shuttle to feel for the filling in a. direction inclined to the longitudinal axis of the shuttle and. is mounted for movement along the filling carrier to call for replenishment of filling, an auxiliary feeler which also enters the shuttle to feel for the filling, and a locking device comprising interengaging members on the main and auxiliary feelers rendered ineffective to lock the two feelers from relative movement during a detecting beat when the auxiliary feeler is the first to engage the filling and rendered ineffective to prevent such relative movement when the main feeler is the first to engage the filling.

In testimony whereof, I have signed my name ,to this specification.
